Class 12 is certainly a critical time in the life of students. To assist students at this difficult time, Toppr provides CBSE previous year question papers. This would enable students to get good marks in exams. Moreover, Toppr makes these question papers easily accessible. This is because; T...
Importance of Solutions in Class 12 Chemistry This chapter discusses the terms related to solutions and solubility. It is a part of the physical chemistry syllabus students study while preparing for NEET. This chapter explains the different types of solutions and their examples. It covers what vapou...
All-metal aromatic monocycles are still rare, in contrast to their ubiquitous organic counterparts, because metal atoms tend to form clusters with multiply bonded atoms instead. Now a planar aromatic Bi5−ring has been synthesized as part of a mixed-valence Co0/CoIinverse-sandwich-type complex....
All Enantioselective synthesis of 2-substituted bicyclo[1.1.1]pentanes via sequential asymmetric imine addition of bicyclo[1.1.0]butanes and skeletal editing Substituted bicyclo[1.1.1]pentanes (BCPs) are widely used as bioisosteres forpara-substituted phenyl rings, providing improved pharmacological prof...
Herein, we have successfully utilized biomass waste ferns contaminated by iron mines, to fabricate a first-of-its-kind high-performance class of Fe single-atom cat-alysts (FeSAC) by a facile pyrolysis. The optimal FeSAC-800 shows an excellent efficiency in the fast-photocatalytic degradation ...
Reaction Mechanism Notes Solutions Notes FAQs on Chemical Kinetics Class 12 Notes NEET Chemistry (Free PDF Download) 1. What is a chemical reaction? A chemical reaction is a process where the atoms of reactants get rearranged to form new products. 2. What is the rate of a chemical reaction...
In view of the very low polyunsaturated fatty acid (PUFA) and monounsaturated fatty acid (MUFA) contents of coconut oil, both the class and concentrations of evolved LOPs were found to be least affected by this partial substitution process. Aldehydic LOPs were greatly suppressed in partially-...

The fungal-derived bicyclo[2.2.2]diazaoctane alkaloids are of interest to the scientific community for their potent and varied biological activities. Within this large and diverse family of natural products, the insecticidal metabolite (+)-brevianamide A
The other prototypical class of mechanically interlocked molecules is represented by rotaxanes. Rotaxanes consist of two main molecular components: a rod-shaped molecule, the axle, threaded through a macrocycle, the wheel. The presence of two bulky groups – the stoppers - at the ends of the ...
